The Lucy spacecraft, on its mission to explore the Trojan asteroids around Jupiter, is currently focusing on the main-belt asteroid Donaldjohanson, as depicted in images shared by NASA on February 25, 2025.
Scheduled for April 20, Lucy's encounter with the 2-mile-wide Donaldjohanson will precede its investigations of Jupiter's Trojan asteroids in 2027.
Lucy, having previously imaged the main-belt asteroid Dinkinesh with its contact-binary moon Selam, is set to unveil new findings with Donaldjohanson.
After launching in 2021, Lucy received a gravity assist from Earth in 2022, paving its way towards the outer solar system for further exploration.
Jupiter's Trojan asteroids are considered remnants from the early solar system, offering valuable insights into planetary formation.
The Lucy spacecraft's extensive voyage will provide key information about the solar system's evolution and history, akin to its fossil namesake, Lucy.
Deputy principal investigator Cathy Olkin highlights Lucy's unique opportunity to study the diverse Trojan asteroids and their formation.
The upcoming encounters with Trojan asteroids mark the first time a spacecraft will explore these ancient relics within Jupiter's orbit.
By unraveling the mysteries of the Trojan asteroids, Lucy aims to enhance our understanding of the broader planetary system's development.
The Lucy spacecraft's ultimate goal is to reach the Trojan asteroids, contributing to significant advancements in solar system exploration.
